先总结一下我的问题（我个人看法，下面有错误详细信息）：就是缺少32位的'libxml2.so.2'，我电脑上只有64位的，apt-get install 提示没有，网上也搜不到。暂时是这个问题，因为我'ldd acroreader'，显示有13个库'not found'，但是现在只提示了这个包。所以在此求个解决方法，谢谢各位大牛:D
接下来是我的安装过程：
我预先安装了32位库：
代码： 全选
sudo apt-get install ia32-libs*代码： 全选
sudo dpkg -i AdbeRdr9.5.5-1_i386linux_enu.deb代码： 全选
/opt/Adobe/Reader9/Reader/intellinux/bin/acroread: error while loading shared libraries: libxml2.so.2: cannot open shared object file: No such file or directory在'/usr/lib/'建立了一个软链，然后终端运行acroreader，又有了新问题：
代码： 全选

结果如下：
